Do's and Don'ts in Whale (鲸) Watching The Department of Fisheries and Oceans has developed guidelines for whale watching in Johnston Strait, where killer whales are found on a daily basis each summer.It is strongly recommended that vessel (船只) operators follow these guidelines for all kinds of whales. ● Approach whales from the side,not from the front or the back. ● Approach no closer than 100 metres,then stop the boat but keep the engine on. ● Keep noise levels down-no horns,whistles or racing of engines. ● Start your boat only after the whales are more than 100 metres from your vessel. ● Leave the area slowly,gradually moving faster when you are more than 300 metres from the whales. ● Approach and leave slowly,avoiding sudden changes in speed or direction. ● Avoid disturbing groups of resting whales. ● Keep at low speeds and remain in the same direction if travelling side by side with whales. ● When whales are travelling close to shore,avoid crowding them near the shore or coming between the whales and the shore. ● Limit the time spent with any group of whales to less than 30 minutes at a time when within 100 to 200 metres of whales. ● If there is more than one vessel at the same observation spot,be sure to avoid any boat position that would result in surrounding the whales. ● Work together by communicating with other vessels,and make sure that all operators are aware of the whale watching guidelines. |
